Added support for python2.7
fix python 3.3 incompatible syntax

there is a bug where source-ing the bin/activate fails with python version 3.3
(probably any 3.0+ version). This small change fixes that. Tested on python versions: 2.6, 2.7, 3.3
Cleanedup python 2.7 implementation, including renaming python2.6 directories to python2.7 where appropriate, fixing up the shebangs in bin/ and including Pillow in anticipation of pending pull request in nupic (numenta/nupic#670)
